One of the first questions homeowners ask when planning a renovation is:


“How much is this actually going to cost?”


And honestly, it’s a fair question.


The challenge is that renovation costs can vary dramatically depending on the home, the level of finishes, structural complexity, site conditions, and how extensive the works are.


On the Gold Coast especially, many homes are older coastal properties or heavily modified over time, which means hidden conditions and construction complexity can influence pricing more than people expect.


In this guide, we’ll break down realistic renovation costs on the Gold Coast in 2026, what affects pricing most, and what homeowners should understand before starting the process.


Average Home Renovation Costs on the Gold Coast


As a general guide in 2026:


  • Cosmetic renovations typically start from around $150,000 to $350,000

  • Mid-level internal renovations often range between $350,000 to $700,000

  • Large-scale renovations and extensions commonly range from $700,000 to $1.5M+


This can include combinations of:


  • Kitchens

  • Bathrooms

  • Structural changes

  • Extensions

  • New roofing

  • Reconfigured layouts

  • Joinery

  • Flooring

  • Windows and doors

  • Outdoor integration

  • Services upgrades


At Barrile Building, many of the renovation and extension projects we work on across the Gold Coast and Northern NSW typically begin from $500k+, particularly where structural work, custom finishes, or larger extensions are involved.

What Impacts Renovation Costs the Most?


1. Structural Changes


Moving walls is one thing.


Changing the structure of a home is another.


Once structural beams, roof modifications, underpinning, slab works, or significant layout reconfiguration are involved, costs can increase quickly due to engineering, labour, temporary supports, and compliance requirements.


This is especially common in older Gold Coast homes where layouts no longer suit modern living.


2. Kitchens and Bathrooms


Kitchens and bathrooms are usually some of the most expensive spaces to renovate because they involve multiple trades working together in a compact area.


Costs can vary significantly depending on:


  • Joinery quality

  • Stone selections

  • Appliances

  • Waterproofing

  • Tiling complexity

  • Plumbing relocation

  • Lighting and electrical upgrades


A high-end kitchen renovation on the Gold Coast can easily exceed $80,000 to $150,000+ depending on detail and finish level.


Bathrooms often range from $30,000 to $60,000+ each.


3. Extensions


Home extension costs on the Gold Coast depend heavily on:


  • Access to the site

  • Existing structure

  • Sloping land

  • Roof integration

  • Services relocation

  • Engineering requirements

  • Level of finish


As a rough guide, quality home extensions in 2026 commonly range from approximately $4,000 to $8,000+ per m² depending on complexity and specification.


The biggest misconception homeowners have is assuming the extension itself is the only cost.

In reality, tying old and new construction together properly is often where much of the complexity sits.

Coastal Homes Can Cost More to Renovate


Many Gold Coast homes are exposed to:


  • Salt air

  • Moisture

  • Strong UV

  • Wind exposure

  • Corrosion


This often means homes require:


  • Marine-grade materials

  • Higher durability finishes

  • Waterproofing upgrades

  • Window replacements

  • Structural repairs

  • Compliance upgrades


Older coastal homes can also reveal hidden issues once demolition begins, including water damage, termite damage, asbestos, or outdated framing methods.


This is why experienced renovation builders place so much importance on early planning and feasibility.


Why Renovation Budgets Blow Out


One of the biggest reasons renovation budgets increase is because homeowners begin construction before fully understanding the scope.


Common causes include:


  • Incomplete documentation

  • Selections not finalised

  • Hidden structural issues

  • Service relocations

  • Design changes during construction

  • Unrealistic allowances

  • Poor early planning


This is why we strongly believe in investing time into pre-construction planning before construction begins.


Clear documentation, realistic budgeting, and early coordination help reduce surprises later.


This is why we place such a strong focus on pre-construction planning and a clear building process before construction begins.


Is Renovating Still Worth It in 2026?


In many cases, yes.


A well-planned renovation can:


  • Improve functionality

  • Increase property value

  • Modernise older homes

  • Improve energy efficiency

  • Create better indoor-outdoor connection

  • Avoid the cost and stress of moving


But not every home should be renovated.


Some properties may be better suited to:


  • Larger extensions

  • Partial rebuilds

  • Knockdown rebuilds

  • Significant reconfiguration


The right path depends on the home, the site, the budget, and your long-term goals.


How to Budget Properly for a Renovation


One of the best things homeowners can do early is separate:


  • “Wish list”

  • “Must have”

  • “Future stage works”


This helps create a more realistic project scope and prevents overcapitalising unnecessarily.


We also recommend allowing contingency for older homes, particularly where demolition has not yet occurred.


Depending on the project, contingency allowances are often around 10% to 15%.
